INTERACTION: A Generative XAI Framework for Natural Language Inference Explanations

Yu, Jialin and Cristea, Alexandra I. and Harit, Anoushka and Sun, Zhongtian and Aduragba, Olanrewaju Tahir and Shi, Lei and Al Moubayed, Noura (2022) 'INTERACTION: A Generative XAI Framework for Natural Language Inference Explanations.', 2022 International Joint Conference on Neural Networks (IJCNN) Padova, Italy, 18-23 July 2022.


XAI with natural language processing aims to produce human-readable explanations as evidence for AI decisionmaking, which addresses explainability and transparency. However, from an HCI perspective, the current approaches only focus on delivering a single explanation, which fails to account for the diversity of human thoughts and experiences in language. This paper thus addresses this gap, by proposing a generative XAI framework, INTERACTION (explaIn aNd predicT thEn queRy with contextuAl CondiTional varIational autO-eNcoder). Our novel framework presents explanation in two steps: (step one) Explanation and Label Prediction; and (step two) Diverse Evidence Generation. We conduct intensive experiments with the Transformer architecture on a benchmark dataset, e-SNLI [1]. Our method achieves competitive or better performance against state-of-the-art baseline models on explanation generation (up to 4.7% gain in BLEU) and prediction (up to 4.4% gain in accuracy) in step one
